Abstract (en)
[origin: US2012302118A1] A sheet for a fiber-reinforced resin according to the present invention includes a conjugate fiber that contains a low melting point polymer component and a high melting point polymer component. The low melting point polymer component and the high melting point polymer component are polymers of the same type. When the sheet is formed into a fiber-reinforced resin molded article, the low melting point polymer component serves as a matrix resin, while the high melting point polymer component serves as a reinforcing fiber. The conjugate fiber is arranged in at least one direction. A fiber-reinforced resin molded article according to the present invention is obtained by heating the sheet for a fiber-reinforced resin to a temperature equal to or higher than the melting point of the low melting point polymer component and lower than the melting point of the high melting point polymer component, followed by compression molding.
